Hello,

I want to get rid of the check engine light on and i was doing some reading that because of the headers they can either tune it out or put a spark plug non-fouler on. What do you guys think is the best way to fix this? I attached a picture of my O2 sensors.

Tune it out if you don't have emissions testing.
